My GF whom I have two children with had an affair and i kicked her out.

I have been going NC as I find no purpose talking to her and I have a faint feeling our youngest child may be this other mans child, when I kicked her out she broke my iPad, threatened to kill herself with a knife and ultimately called DHS to try to get me in trouble after she was booted.

(Deleted all social media last night of mine) Was forward to today she has been messaging me to get some of her stuff which I ignore, as I know it's a way to get into my condo and see me.

As I am walking home from the gym I see her car parked near one of the entrances to my condo and I'm like fuck.. well she walked out of the buzz in area and saw me when I immediately turned my back walked the other way and ran to the next entrance to go inside.

She started buzzing my door competently, left, sent emails claiming she was going to the police, came back buzzed more, some how got into the entrance of my building banged on my door for no shit an hour kicking and kicking, ringing the door bell and ultimately leaving.

Fast forward tonight I get an email from a friend that this girl made a public Facebook post with my name, address, photo putting me on blast as an abusive, bad dad, that I did this and thst to her while everyone is posting you go girl.

What should I do and why the fuck did she do this?

I ended up packing all her shit up last night and leaving it on her porch, and deleting all my social media
